Aloha carolese,
You can go right into the Level Two course and work with any section you choose.
Master Lin teaches Level One and Two back to back. You can be learning the active exercises from Level One and learning and practicing the healing steps of Level Two at the same time. Working on others assists your own healing and growth.
There are a lot of helpful technique in the Level Two course which you can do yourself, and actually, you can work on yourself with the Level Two healing steps as well. Just find yourself a mirror, or visualize your body in the chair in front of you.
Much Love,
Shawn
